DW- Thanks for the gas law info. I suk at teh maff, but I understand the principles.

Hobie- I am curious about your IAT sensor, as it SHOULD be detecting temperature changes. Perhaps it's reading more the IC metal temp than the actual intake charge? Again let me stress the "respectfully" part as I am days from ordering my Megasquirt and EFI hardware, and your experience and friendship will be invaluable.
